Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a manufacturing method of a double
chamber aerosol container used where contents, such as hair care
products, cosmetics, antiperspirant-deodorants, other human body
treatment products, insecticides, coating materials, cleaners, and
other products for household, industrial materials, automobile
goods, medicines, foods, and so on, are filled in an inner sack and
where a propellant is filled in an outer container below a mountain
cup or container cap.
2. Description of Related Art
Containers in which an inner sack filled with contents is mounted
within an outer container and its volume is reducible according to
reduction of the contents, have been known previously. In a
double-chamber aerosol container, any direct contact between the
propellant and the aerosol contents is not favorable.
In such a conventional double chamber aerosol container, the inner
sack is attached inside the aerosol container where an edge of an
orifice of the inner sack is engaged with a bead portion of the
aerosol container and where the lower end of the inner sack is in
contact with the bottom of the aerosol container. Contents only,
without any propellant, are filled within the inner sack thus
mounted.
After those contents are filled, the container cap is fitted inside
the inner sack. After an upper opening of the inner sack is
disposed at a space between the container cap and the bead portion
of the aerosol container, the inner sack and the container cap are
lifted upward to form a filling gap for the propellant between the
outer periphery of the opening of the inner sack and the bead
portion of the aerosol container, and thereby the propellant is
filled within the aerosol container via the filling gap.
With this conventional method, however, the exterior is in air
communication with the inside of the inner sack, because the
contents are placed in the inner sack where the inner sack before
the container cap is fitted is mounted within the container. If the
contents are filled in such a circumstance, the contents may be
spilt out when the container cap is fitted where the contents are
filled up closely to the opening of the inner sack. On the other
hand, if the contents are filled in a smaller amount, air may
remain in the inner sack, and as a result, the contents may be
oxidized or deteriorated.
Where the contents are agent type using an isopentane in a gel form
or the like, the contents may be deteriorated due to contacts with
the open air, or the isopentane may evaporate and generate bubbles
where the temperature of the isopentane increases due to contacts
with the open air, and those raise problems during such filling
work. In case the open air contacts with the contents, such
contacts are not favorable for medicines, cosmetics, foods, and so
on for which prevention of contamination is strongly demanded.
The inner sack is in a state that the bottom of the inner sack is
in contact with the inner surface of the bottom wall of the aerosol
container to endure the weight of the contents when the contents
are filled where the inner sack is mounted within the aerosol
container. The bottom end of the inner sack thus contacts with the
bottom of the aerosol container, so that the inner sack is
advantageously stably disposed within the aerosol container in
opposing to the weight of the contents.
In case the inner sack extends longer than the standard size due to
manufacturing deviations of the inner sack or extensions of the
material, however, the bead portion of the aerosol container is not
properly in contact with the outer peripheral surface of the inner
sack, thereby frequently rendering the inner sack inclined or
projected upward. In such a case, sealing may become inadequate
during clinching between the container cap and the bead portion at
the final process. In case the inner sack is formed shorter than
the standard size, the inner sack may accidentally drop in the
aerosol container, and disadvantageous problems for the
manufacturing process may happen frequently.
SUMMARY OF THE INVENTION
It is an object of the invention, from a viewpoint to solve the
problems above, to provide a manufacturing method of an aerosol
container capable of preventing contents from contacting with open
air during filling of the contents to keep the contents away from
deterioration or the like due to oxidation of the contents.
It is another object of the invention to provide a manufacturing
method of an aerosol container not subject to overfilling or
shortage of filling of the contents and, even if subject to
shortage of filling, not subject to oxidation due to contacts
between the open air and the contents.
It is yet another object of the invention to provide a
manufacturing method of an aerosol container in which a bead
portion of the aerosol container and an outer peripheral edge of an
opening of a container cap and an inner sack are surely engaged
with each other and in which such an engagement secures the
container cap by clinching it so as not to create leaks and
prevents the contents from deteriorated due to oxidation.
The foregoing objects are accomplished with an aerosol container
including: an outer container having a hollow interior and a bead
portion formed on a surface of the outer container; an inner sack,
whose volume is reducible according to reduction of contents,
inserted in the hollow interior of the outer container to be
mounted, the inner sack having an opening for containing the
contents; and a container cap, to which a valve assembly is
disposed, fitted in an inner periphery of the opening of the inner
sack and engaged with the bead portion of the outer container for
constituting, together with the inner sack, a liquid container,
wherein a lower end of the inner sack is not in contact with a
bottom of the hollow interior of the outer container.
In another aspect of the invention, a method for manufacturing a
double chamber aerosol container has the steps of: inserting a
container cap, to which a valve assembly is disposed, in an inner
periphery of an opening of an inner sack, whose volume is reducible
according to reduction of contents, to fit the container cap at the
opening, the inner sack and the container cap constituting a liquid
container; inserting the inner sack in an outer container upon
temporarily fitting the container cap to a bead portion of the
outer container without immovably securing the container cap to the
bead portion; coupling the outer container with a filling head for
a propellant where a lower end of the inner sack is not in contact
with a bottom of a hollow interior of the outer container; lifting
the container cap upward from the bead portion to form a filling
gap between the container cap and the bead portion; introducing the
propellant into the outer container via the filling gap; securing
the container cap and the outer container to each other by way of
the opening of the inner sack upon immobilizing the container cap
by clinching the container cap to the bead portion; and filling the
contents within the inner sack by way of the valve assembly.
According to a preferred embodiment, the container cap is fitted
immovably in the opening of the inner sack. The container cap is
preferably fitted by, while the inner sack is suspended, frictional
force not making the inner sack drop due to the weight of the inner
sack. A communication gap for a propellant in a size of 0.01 to
1.00 mm may be formed between an inner peripheral surface of the
bead portion and an outer peripheral surface of the inner sack.
To manufacture the double chamber aerosol container thus
constituted, first, the container cap is inserted as to fit to the
inner sack in which the contents are filled before the contents are
filed in the sack. The container cap is fitted to the inner
periphery of the opening of the outer container. This fitted state
can be an immobilized state such as adherence or welding between
the container cap and the inner sack or be made by coupling with
fitting force of a degree that the inner sack does not drop from
the container cap due to the weight of the inner where the inner
sack is suspended to an outer periphery of the container cap. The
container cap is formed with the valve assembly including a stem, a
housing, and so on.
The inner sack thus connected to the container cap is then mounted
within the outer container upon engagement with the bead portion of
the outer container. In this state, the lower end of the inner sack
is made in a size so as not to contact with the inner surface of
the bottom of the outer container. The inner sack therefore avoids
improper contact with the bead portion caused by contacts with the
bottom of the outer container, so that the container cap and the
inner sack can be surely mounted on the bead portion.
In case the container cap is thus mounted to the outer container,
the container cap is not secured to but temporarily fitted to the
outer container, and the contents are not yet filled in the inner
sack. Accordingly, even if the lower wall of the outer container
does not contact or support the lower end of the inner sack, the
container cap adequately holds and engages the inner periphery of
the opening of the inner sack. It may be done with frictional force
that makes the inner sack not to drop by its weight in the
condition that the inner sack is suspended.
In a case where force in a separating direction may be exerted to
the inner sack and the container cap, such as, a case that many
container caps coupled to respective inner sacks are placed in the
same container, or that such a sack is mounted with high speed to
the outer container by means of an automation machine, the
container cap may preferably be immovably inserted and secured to
the inner periphery of the opening of the inner sack.
As described above, the filling head is connected to the top of the
container cap where the container cap coupled to the inner sack is
temporarily fitted to the bead portion of the outer container, and
the filling gap for the propellant is formed between the container
cap or the inner sack and the bead portion by pulling the container
cap and the inner sack upward.
After the propellant is filled in the outer container by way of the
filling gap for the propellant, the container cap is clinched to
the bead portion of the outer container, thereby sealing the outer
container and making the outer container, the container cap, and
the inner sack secured in a united body.
The contents are filled in the inner sack by a through-valve method
by way of the valve assembly secured to the container cap.
This invention thus can make the inside of the inner sack not in
contact with the open air since the container cap and the inner
sack are in an engagement state before those are mounted within the
outer container. The contents are filled by way of the valve
assembly, and therefore, when filled in the inner sack, the
contents can be filled without contacting with the open air and
avoid overfilling. Thus, there will be no problem where contents
easily oxidized or contents such as gel foams generating bubbles
from increase of temperature due to contacts with the open air are
filled. Because this invention allows the contents to be filled
without contacting the open air, it is particularly favorable for
medicines, cosmetics, foods, and so on, in which prevention of
contamination is strongly demanded.
Coupling between the container cap and the bead portion is in a
state forming a gap where the lower end of the inner sack is not in
contact with the lower end of the outer container, and therefore,
the inner sack never pushes up the container cap as to incline the
container cap. The container cap and the inner sack can be surely
fitted at the proper place with respect to the bead portion of the
outer container, and the container cap and the outer container are
surely secured by clinching the container cap to the bead portion
after the propellant is filled, thereby preventing gases from
leaking. Because the container cap and the inner sack are in the
engagement relation before those are mounted in the outer
container, those are easily handled, and the work productivity can
become very high.
The contents to be filled in the inner sack are, as hair care
products, hair sprays, hair treatments, hair shampoos, hair
conditioners, acidic hair dyes, oxidizing two-agent type permanent
hair dyes, color spray-decolorant, agents for permanently waving
treatment, hair restorers, hair foams, hair tonics, sprays for
correcting bad hair, fragrances for hair, and so on.
As cosmetics, exemplified are shaving creams, after-shave lotions,
after-shave gels, perfumes and Eau de Colognes, facial cleansing
agents, sunscreens, beauty washes, foundation creams, depilatories,
decolorants, bath gels, toothpastes, skin care foams, and so
on.
As deodorants and antiperspirants, exemplified are, e.g.,
antiperspirants, deodorants, body shampoos, etc. As other human
body treatment goods, exemplified are muscular antiphlogistics,
skin disease treatments, dermatophytosis medicines, insect
repellents, cleaners, oral agents, salves, burning medicines,
etc.
As insecticides, exemplified are, e.g., air-spray insecticides,
insecticides for cockroach, insecticides for gardening,
insecticides for ticks, pesticides for noxious insects, etc. As
coating agents, exemplified are, e.g., paints for house, paints for
automobile, undercoating agents, etc.

cleaners, bath cleaners, floor and furniture cleaners, shoe and
skin cleaners, wax cleaners, etc. As other goods for household,
exemplified are, e.g., room deodorants, deodorants for toilet,

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to the drawings, a double chamber aerosol container and a
method for manufacturing the aerosol container are described.
Numeral 1 is an inner sack and is formed of a soft material so that
the volume is reducible according to reduction of the contents
filled therein or formed in a pleated shape. A container cap 4 to
which a valve assembly 3 is disposed is inserted and secured to an
inner periphery of an opening 2 of the inner sack 1 as shown in
FIG. 1.
The container cap 4 and the inner sack 1 can be secured not to
separate from each other by a method such as use of adhesive or
welding. The inner sack 1 may be fitted to the container cap 4 by
frictional force of a degree that the inner sack 1 does not fall by
its weight from the container cap 4 where the inner sack 1 is
suspended at an outer periphery of the container cap 4.
The valve assembly 3 can be constituted of a known structure, and
in this embodiment, as shown in FIG. 10, a housing 5 is secured at
the center of the container cap 4, and a stem 7 that is urged
outward by a coil spring 6 is inserted in this housing. Since an
orifice 8 of the stem 7 is sealed with an inner peripheral surface
of a ring-shaped gasket 10, the inside and outside of an outer
container 13 are not in communication with each other unless the
stem 7 is pressed, and therefore, the assembly 3 prevents contents
11 from spraying out. The inner sack 1 and the container cap 4
constitute a liquid container 12.
Air in the inner sack 1 is vacuumed and discharged outside where
the stem 7 of the valve assembly 3 is pressed and released as shown
in FIGS. 3, 4 before the inner sack 1 is attached in the outer
container 13 to remove the air in the inner sack 1. This discharge
of the air in the inner sack 1 is not necessarily made, and it is
enough that the air in the inner sack 1 of a considerable volume is
discharged. The inner sack 1 is preferably vacuumed but not
necessarily made. The inner sack 1 thus vacuumed is inserted within
the outer container 13 in association with a bead portion 14. In
case air in the inner sack 1 is discharged, an outer diameter of
the inner sack 1 is made smaller than an inner diameter of the bead
portion 14, so that the sack 1 is inserted in the outer container
without causing any problem.
The container cap 4 and the inner sack 1 are mounted in the outer
container 13 as shown in FIG. 5, and the container cap 4 is made in
contact with the bead portion 14 of the outer container 13. This
contact is so done, as shown in FIG. 5, that an upper end of the
inner sack 1 is placed between the container cap 4 and the bead
portion 14. The lower end of the inner sack 1 in this state is made
not in contact with the bottom surface of the interior of the outer
container 13. Since the lower end of the inner sack 1 is thus made
not to contact with the inner surface of the bottom 15 of the outer
container 13, the inner sack 1 is never pushed up or inclined due
to contact with the bottom 15 of the outer container 13, so that
the container cap 4 is surely made in contact with the bead portion
14 of the outer container 13.
In case the container cap 4 is mounted on the outer container 13, a
communication gap 16 for propellant of 0.01 to 1.0 mm is formed as
shown in FIG. 7 at a space between the outer periphery of the
opening 2 of the inner sack 1 and the bead portion 14. In case the
inner sack 1 is attached in the outer container 13, the container
cap 4 and the outer container 13 are temporarily fitted without
being secured to each other.
The inner sack 1 is inserted thus in the outer container 13, and
where the container cap 4 and the bead portion 14 are temporarily
fitted to each other, as shown in FIG. 6, a filling head 17 is
mounted on a top of the outer container 13, and by operation of the
filling head 17, the container cap 4 is lifted upward. This can be
made by vacuuming or by mechanical operation. Where the container
cap 4 is thus suspended, a filling gap 18 for propellant is created
between the bead portion 14 and the container cap 4. Air in the
outer container 13 is removed outside by vacuuming through the
filling gap 18 while the filling gap 18 is created.
Subsequently, as shown in FIG. 8, the propellant such as nitrogen
is filled with pressure in the outer container 13 via the filling
gap 18 for propellant. By this filling of the propellant, the inner
sack 1 surely enters in a contracted state as shown in FIG. 8.
After this contraction, as shown in FIGS. 9, 10, the bead portion
14 of the outer container 13 and the container cap 4 are clinched
to surely secure the container cap 4 to the outer container 13. In
this secured state, the end of the opening of the inner sack 1 is
placed between the container cap 4 and the bead portion 14, thereby
serving as a packing for the inner sack 1.
After the container cap 4 is clinched, a pin hole examination is
performed for finding pinholes or the like in the inner sack 1.
This pin hole examination is made by measuring gas components drawn
by vacuuming upon vacuuming the inner sack 1 where the stem 7 is
pressed to open the valve assembly 3 as shown in FIG. 11. If any
propellant is simultaneously withdrawn from the valve assembly 3,
the inner sack 1 has some pinhole, and the product will be
eliminated from this manufacturing process.
If no extraordinary matter is found in the inner sack 1 during this
pin hole examination, as shown in FIG. 12, the filling head 17 for
contents 11 is coupled to the valve assembly 3, and the contents 11
are filled in the inner sack 1 via the valve assembly 3. This
filling allows the contents 11 not to contact with air because the
inner sack 1 is held in a surely sealed state via the valve
assembly 3. Therefore, there will be no problem even where a hair
dye agent that may produce oxidation upon contacts with the air is
filled in the inner sack 1 or where a gel foam using an isopentane
or the like generating foams upon contacts with the air is filled.
Filling of the contents 11 is completed where the contents 11 are
filled in the inner sack 1 and where the pressures in the inner
sack 1 and the outer container 13 are equalized.
The inner sack 1 increases its volume equally in a width direction
by widening the pleat when the contents 11 are filled. The inner
sack 1 is formed of a polyethylene resin, which prevents the filled
contents 11 from leaking in the outer container 13 and the
propellant from entering into the inner sack 1.
Where the outer container 13 thus manufactured is manipulated, the
contents 11 are well sprayed out by pressure of the propellant
exerted to the entire outer peripheral surface of the inner sack 1
where the contents 11 are sprayed. Because the inner sack 1 has the
pleats, the inner sack 1 is stably contracted according to
reduction of the contents 11 in association with pressure given by
the propellant. Consequently, spraying can be continued constantly
until the end of the spraying, and the contents 11 can be sprayed
without any waste.
Although in the above embodiment the inner sack 1 is made of the
polyethylene resin, it can be made of polypropylene resin,
polyethyleneterephthalate resin, polyacrylonitrile resin, and the
like. The inner sack 1 can be formed in a single layer structure
using a single kind resin as described above, and an inner sack 1
of a multiple layer structure can be formed by overlaying multiple
resins. For example, an ethylene-vinylalcohol copolymer is disposed
on an outer surface of the polyethylene resin, and another
polyethylene resin is disposed over the surface to form an inner
sack 1 of a multiple layer structure. As another embodiment, a
polyethyleneterephthalate resin is disposed on an outer surface of
the polyethylene resin, and another polyethylene resin is disposed
on the surface to form an inner sack 1 of another multiple layer
structure. In any case of the above examples, the inner sack 1 is
formed properly of a material having a durability against the
contents and components of the propellant.
The followings are prescriptions of the respective contents 11
where hair care products, cosmetics, deodorants, antiperspirants,
other products for human being, insecticides, and household
products are filled in the above inner sack 1. The propellant
filled in the outer container is a gas of one kind or a mixture gas
of multiple kinds selected from compression gases such as nitrogen,
carbonate gas, suboxide nitrogen, air, etc., and liquid gases such
as liquid petroleum gas, and diethylether, etc.

treatment, a tonic, and a hair-restorer.

Since this invention is thus constituted, the contents in the inner
sack are never in contact with the open air, and the contents are
surely filled in the inner sack where the air is cut off during the
manufacturing process. Therefore, even if the contents filled in
the inner sack are readily oxidized, or are medicines, cosmetics,
foods, and so on, which are readily subject to contamination in
contact with the open air, or are materials that generate bubbles
by temperature increase due to contacts with the open air, the
contents can be surely filled without being deteriorated.
Because the inner sack is set such that the lower end of the inner
sack is not in contact with the bottom of the outer container, the
container cap is surely engaged with the bead portion, thereby
preventing the sealing from breaking due to inclination of the bead
portion.
Since the inner sack and the container cap enter in an engagement
relation before those are mounted in the outer container, the inner
sack is readily set in the outer container during the manufacturing
process and renders manufacturing productive and flawless.
The foregoing description of preferred embodiments of the invention
has been presented for purposes of illustration and description,
and is not intended to be exhaustive or to limit the invention to
the precise form disclosed. The description was selected to best
explain the principles of the invention and their practical
application to enable others skilled in the art to best utilize the
invention in various embodiments and various modifications as are
suited to the particular use contemplated. It is intended that the
scope of the invention should not be limited by the specification,
but be defined by the claims set forth below.
